For your question, I'm sorry to inform that you cannot renew your 3 seats subscription to 1 seat. We've checked your account information and confirmed that your Auto-Renewal still enable. We suggest canceling Auto Renewal, and purchase a 1 seat subscription of Maximum Security. We have a support document which describes how to cancel Auto Renewal: Frequently asked questions (FAQs) about Auto-Renew - refer to "Disabling or Canceling Auto Renewal"
